No impact on leveling. But what I don't like is that the side closest got the camera is higher than the side farther away. this tells me the column is not plumb. It might not be a concern if you have to installed the top triangle yet but if you have check the towers with a large framing square if you have one - even a small square is better than nothing.

In general the ends are cut square but perhaps this one wasn't so check that to rule it out too.

I have indeed installed the top triangles and am working on tensioning the belts.

I don't have the best tools to with, but I have a level and used that; assuming its right angles are accurate then it appears I may have some slight lean in one vertical extrusion. When installing the top triangle I did have issues with one extrusion not lining up properly.
